- said flaps comprise an axis of rotation, in particular extending in the direction of their longitudinal conformation
- said flaps comprise so-called external front surfaces intended to be exposed to the incident air flow, in the closed position of the flaps, said external front surfaces being disposed on either side of said axis of rotation in an equivalent manner in size; so that the incident airflow creates pairs compensating each other on said outer front surfaces of the flaps,
- said flaps comprise rear surfaces, said external, intended to be exposed to said depression, in the closed position of the flaps, said external rear surfaces being disposed on either side of said axis of rotation differently in size, so that said depression generates a rotational torque causing the flaps to open,
- said flaps overlap from one another to the closed position of the flaps, so that relatively to said axis of rotation a lower part of one covers a substantial part of an upper part of the other, or even the whole of the upper part of the other,
- said overlapping portions have a covering recess from one to an edge of the other
- said axis of rotation of a flap is located near the rear edge of the adjacent flap, in the closed position of the flaps,
- said device comprises means for controlling the opening / closing of the shutters
- control means are of the type comprising a rod connected to said flaps, itself actuated by means of an actuator, for example driven by an electric motor,
- control means are configured to maintain the flaps in the closed position during normal operation of said control means, despite said rear depression,
- said device is configured to allow the opening of the flaps in the event of failure of said control means, in particular their power supply, in other words said rotational torque causing the opening of the flaps facing said depression is greater than a holding torque flaps in the closed position in the event of failure of said control means,
- said device comprises a return spring when the shutters open increasing said rotational torque causing the flaps to open.
- the invention also relates to a ventilation duct comprising said device for controlling the flow rate of an air flow for a motor vehicle.
- Said ventilation duct is intended to be advantageously disposed on the front face of the vehicle, in particular facing a front calender opening of the vehicle.
- Said depression is interlocked in particular in the event of failure of said control means.
- Said depression is generated by a fan, in particular associated with said ventilation duct.
- Said fan may be configured to generate an air flow for passing through heat exchangers downstream of the duct.
- FIG. 1 is a perspective view of a front-end ventilation duct of a motor vehicle according to one embodiment of the invention
- FIG. 2 is a schematic transverse partial sectional view of the ventilation duct according to FIG.
- the invention relates to a device 1 for controlling the flow rate of an air flow F for a motor vehicle, in particular for a front face of the motor vehicle.
- This device 1 is here mounted on a ventilation duct C. It comprises a plurality of shutters 3 for controlling the flow rate of said air flow F, rotatably mounted on a support of said device, here a frame 5 intended to be mounted on a frame of the vehicle.
- Said device 1 comprises means for controlling the opening / closing of the shutters, not shown.
- These control means may be of the type comprising a rod connected to said flaps 3, itself actuated via an actuator, in particular driven by an electric motor.
- This device is for example intended to cool vehicle equipment, not shown, such as heat exchangers, including cooling radiators or heat exchangers of a heating loop and / or air conditioning of the passenger compartment of the vehicle, which are placed at the front of the vehicle and which are traversed by said air flow.
- heat exchangers including cooling radiators or heat exchangers of a heating loop and / or air conditioning of the passenger compartment of the vehicle, which are placed at the front of the vehicle and which are traversed by said air flow.
- the flaps 3 are provided with a rear cover R, in the closed position of the flaps, extending from one to the other flaps , so as to allow the opening of said flaps under the action of a depression D, shown by an arrow, present at the rear of said device.
- Said depression D is in particular generated by a fan, not shown, disposed at the rear of said flaps.
- This depression is advantageously applied transversely to the shutters in the closed position in the direction of the arrow. It is notably implemented in the event of failure of said shutter opening / closing control means, in closed shutter position, when the vehicle engine is heating up. The vehicle engine can then be cooled by the flow of air F passing through said forced device in the open position of the flaps.
- the flaps 3 are of longitudinal conformation, for example rectangular or near. They are advantageously of constant thickness, so that their mass is distributed homogeneously over their entire surface.
- these flaps may have a recovery before the one of the flaps. Said covering is insensitive to pressure, in the closed position of the flaps, so that the rolling of the vehicle has no effect for the opening of the flaps.
- these flaps comprise an axis of rotation 13, extending in the direction of their longitudinal conformation, here in the middle part of their surface. They comprise in particular front surfaces 15a, 15b said external, exposed to the incident air flow V in the closed position of the flaps, for example the relative air flow to the front of the vehicle when the latter rolls.
- the external front surfaces 15a, 15b of a flap which are disposed on either side of the said axis of rotation 13 are equivalent in size, so that the incident air flow creates obstacles. couples at the opening of the flap compensating each other on each of them. Thus, the incident airflow has no effect on the flap opening.
- the flaps 3 comprise rear surfaces, said external.
- the outer rear surfaces exposed to said depression 17a, 17b of a flap, in the closed position of the flaps, which are disposed on either side of said axis of rotation 13, are different in size, so that said depression generates a torque rotation on the flap in the direction of opening the flaps. This difference is shown schematically to the right of the two flaps 3 in FIG.
- said flaps overlap one another, according to said covering R, so that relatively to said axis of rotation a lower portion 3a of one covers a substantial portion of the upper portion 3b of the other or even the whole of the upper part 3b of the other.
- the effect of the depression in opening flaps is even greater than the recovery R flaps is larger.
- Said overlapped flap portions 3a, 3b are advantageously applied flat on one another, in particular transversely to the depression, as here, which gives a full effect of the depression on the flaps.
- Said axis of rotation 13 of a flap may, as here, be located near the rear edge 19 of the adjacent flap.
- Said device may also be configured to maintain the flaps in the closed position, in normal operation of said control means, so that the flaps do not open despite said rear depression. More particularly, according to the invention, the device is configured to allow the opening of the flaps in case of failure of said control means, in particular their power supply, here the power supply of the actuator. This flap opening is of a safety order for the vehicle, in particular as to the cooling of the vehicle engine.
- Said rotation torque in opening of the flaps facing said depression, engaged in this case is in particular greater than a holding torque flaps in the closed position, for example the return torque due to gravity and / or the resisting torque of friction of the rotation of the flaps, from the closed position to the open position.
- Said rotation torque, applied on the axis 13 is able to overcome said resisting torque, applied in the opposite direction on the axis 13, and thus to allow to open the flaps in case of failure of said control means.
- Said device may comprise a return spring at the opening of the flaps, not shown, increasing said rotational torque in flap opening.
- the invention also relates to the ventilation duct C comprising said device 1 for controlling the flow rate of an air flow for a motor vehicle, as illustrated in FIG.
- the duct comprises an outer channel 2 of substantially convergent shape towards the shutters from upstream.
- Said channel is configured to join, upstream, a calender grid (not shown) to prevent a possible introduction of foreign bodies; it carries, downstream, the device with its series of shutters 3 positioned parallel to one another above. These are particularly arranged so that in the closed position, they obstruct the opening of the conduit.
- This ventilation duct C may incorporate the calender 5 of the vehicle, upstream of the device, as well as said fan downstream of the device, which may be connected in particular to said shutter control means to allow said vacuum to be engaged in case of failure. control means. Such a trip may also be caused by a vehicle engine control unit.
- the invention thus provides a simple solution to allow a safety cooling of organs of a motor vehicle, in particular by a front face of a vehicle.
